Definitions
- the fracture of an elongated bone such as a femur or humerus
- a plate to the fractured bone across the fracture.
- the plate extends across the fractured area and thus stabilizes the fractured components of the bones relative to one another in a desired position.
- the plate can be removed or left in place, depending on the type of plate that is used.
- Another type of stabilization technique uses one or more elongated rods extending between components of a bone structure and secured to the bone structure to stabilize the components relative to one another.
- the components of the bone structure are exposed and one or more bone engaging fasteners are placed into each component.
- the elongated rod is then secured to the bone engaging fasteners in order to stabilize the components of the bone structure.
- One problem associated with the above described stabilization structures is that the skin and tissue surrounding the surgical site must be cut, removed, and/or repositioned in order for the surgeon to access the location where the stabilization device is to be installed. This prepositioning of tissue causes trauma, damage, and scarring to the tissue. There are also risks that the tissue will become infected and that a long recovery time will be required after surgery for the tissue to heal.
- Minimally invasive surgical techniques are particularly desirable in, for example, spinal and neurosurgical applications because of the need for access to locations within the body and the potential trauma to vital intervening tissues.
- the development of percutaneous minimally invasive spinal procedures has yielded a major improvement in reducing trauma, recovery time and post-operative pain.
- the benefits of minimally invasive techniques have also found application in surgeries for other locations in the body where it is desirable to minimize tissue disruption.
- minimally invasive techniques One potential disadvantage associated with minimally invasive techniques is that the tissue can obstruct access and visualization of the implantation location for an implant in the body of the patient. Accordingly, the optimally sized implant for implantation between anchors or other structures in the patient may not be readily determinable. While minimally invasive techniques have yielded benefits, there remains a need for instruments and methods that facilitate application of minimally invasive procedures during surgery.
- an apparatus comprises a first arm having a distal end adapted to engage a first bone screw, and a proximal end comprising a graduated scale.
- a single pivot pin is operably engaged with the first arm between the distal end and the proximal end thereof.
- the apparatus also comprises a second arm operably engaged with the first arm via the single pivot pin.
- the second arm has a distal end adapted to engage the second bone screw, and a proximal end comprising an indicator segment slidably engaged with the graduated scale. Therefore, a position of the indicator segment relative to the graduated scale may be indicative of a spacing between the first and second bone screws.
- a system for percutaneous implantation of spinal instrumentation comprising a first bone screw extender adapted to implant a first bone screw at a first bone structure and a second bone screw extender adapted to implant a second bone screw at a second bone structure.
- a caliper is also provided for measuring spacing between first and second bone screws engaged with first and second bone structures, wherein the caliper comprises a first arm having a distal end adapted to engage the first bone screw extender, and a proximal end comprising a graduated scale extending therefrom.

- a position of the indicator segment relative to the graduated scale may therefore be indicative of the spacing between the first and second bone screws, allowing a surgeon to accurately determine a length of spinal rod to be inserted to connect the first and second bone screws.
- a method for measuring spacing between first and second bone screws engaged with first and second bone structures.
- the method comprises engaging a first bone screw extender with the first bone screw, engaging a second bone screw extender with the second bone screw, and pivoting a first arm and a second arm of a caliper relative to one another about a single pivot pin operably engaged with the first and second arms, such that the first and second arms of the caliper are insertable into the first and second bone screw extenders.
- the method further comprises inserting the first arm of the caliper into the first bone screw extender, wherein the first arm has a distal end configured to engage the first bone screw extender, and a proximal end comprising a graduated scale extending therefrom.
- the method further comprises inserting the second arm of the caliper in the second bone screw extender, wherein the second arm has a distal end configured to engage the second bone screw extender, and a proximal end comprising an indicator segment slidably engaged with the graduated scale of the first arm. Therefore, a position of the indicator segment relative to the graduated scale may be indicative of a spacing between the first and second bone screws.

- the second arm 20 also has a distal end 22 adapted to engage the second bone screw P2 (in some instances, via the bone screw extender 50, as shown in Figure 4), and a proximal end 26 comprising an indicator segment 25 slidably engaged with the graduated scale 15 such that a position of the indicator segment 25 relative to the graduated scale 15 is indicative of a spacing S between the first and second bone screws PI, P2 (see Figure 3, for example, where the spacing S is shown between distal ends 41, 51 of the bone screw extenders 40, 50, respectively).
- the distal ends of the first and second arms 10, 20 may also comprise cylindrical elements 12, 22 configured to be insertable into a first bone screw extender 40 and a second bone screw extender 50 (see Figure 3, for example) extending respectively from the first and second bone screws PI, P2 (see Figure 5, for example).
- the distal ends of the first and second arms 10, 20 may also comprise stop elements 1 1, 21 formed thereon that may ensure that the cylindrical elements 12, 22 extend only a selected distance into a complementary set of cylindrical bores defined in the bone screw extenders 40, 50.
- the extreme distal ends of the cylindrical elements 12, 22 may also be formed with a conical and/or tapered shape so as to ease the insertion of the cylindrical elements 12, 22 into the screw extenders 40, 50.
- the distal and proximal ends 12, 16 of the first arm 10 may be assembled and/or formed to be substantially parallel.
- the first arm 10 may be substantially straight along its length.

- the graduated scale 15 may comprise an arcuate member extending from the proximal end 16 of the first arm 10.
- the second arm 20 may comprise a proximal end 26 comprising an indicator segment 25 slidably engaged with the graduated scale 15 such that a position of the indicator segment 25 relative to the graduated scale 15 is indicative of a spacing S between the first and second bone screws P I, P2.

- the indicator segment 25 may define a window or other aperture through which the markings 17 of the graduated scale 15 may be visible to a surgeon, wherein the markings 17 are indicative of a length or other spacing S measurement between adjacent bone screws P I, P2 as indicated by the relative positions of the distal ends 12, 22 of the arms 10, 20 of the caliper 1.
- the markings 17 may be printed, etched, cut or otherwise made visible on the graduated scale and may be calibrated to adjust for variations in the geometry of the arms 10, 20, the position of the pivot pin 30 and/or whether or not bone screw extenders 40, 50 are present between the distal ends 12, 22 of the arms 10, 20 and the bone screws PI, P2.
